HEEL-CUTTING APPARATUS.

Application filed January 11, 1917.

To all whom it may concern:

Be it known that I, WILLIAM J .Nnscrr'r, a citizen of the United States residing t Los Angeles, county of Los An geles, State of California,have invented a certain new and useful Heel-Cutting Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention,

to which it appertains make and use the same.

This invention relates to heel cutting apparatus; form of the apparatus-which is disclosed in my application filed Nov. 20, 1916, SenNo. 132,486. l 1

One object of the invention is to provide a modified form of heel consisting of a novel and improved construc tion, arrangement, and combination of parts and devices. 1

Further objects of the invention are to provide a novel and improved heel cutting apparatus which is comparatively simple in construction, economical to manufacture, compact and light in weight, easy and convenient to operate, and eifectivein use.

Other objects and the advantages of the invention will be apparent to those skilled inthe art from a careful consideration of the following description of the preferred construction embodying the invention, taken in connection with the accompanying drawin' 's in which *igure l'is aside elevational View of the modified heel cutting apparatus; Fig. 2 is an enlarged broken sectional View taken on the line 2-2 of Fig. 1; Fig. 3 is a cross sectional View taken on the line 3-3 of Fig. 2; Fig. is a broken sectional view taken on the line4-4 of Fig. 1; Fig. 5 is an enlarged side elevational view of a portion of the apparatus; Fig. 6 isa broken sectional View taken on the line 6+6 ofFig. 5; Fig. 7 enlarged plan view of a portion of the apparatus; Fig. 8 is an enlarged broken side elevational view of one of the heel holding jaws; and Fig. 9 is a'plan view of the same. The supporting frame 10 has thereon the forwardly extending arm 11 to which is secured the stationary horizontal shaft 12. A

sleeve 13 is 'slidably fitted on the shaft 12 and it is provided with an annular groove 14 in whichis fitted the ring '15 which latter has thereon theprojections or pins 16 which Specification ofLetters Patent.

1 are fitted in the of America,

such as will enable others more particularly to a modified cutting apparatus Patented Sept. 4, 1917.. Serial N0.141,894.

slots 17 of the split ring 18 which has on its forward end the extension 19 and has on its rear end the extension 20 which latter is connected by the pivot 21 to the projection 22 on the arm 11. The extension 19 is provided with the handle 23. A latch 24is mounted on the pivot 25 between the ears 26 on the extension 19, and it is provided with teeth adapted to engage the teeth 27 on the arcuate rack 28 which is suitably mounted on the arm 11. A spring 29 is adapted to normally hold the latch 24 in engagement with the teeth 27 tothereloy lock the sleeve 13 in adjusted position.

On the sleeve 13 is mounted to swing in a vertical plane the arm 30 which at its up per end is provided with the socket 31 in which is pivotally fitted the part 32 which carries thepivot 33 on which is tiltably mounted the bar 34 which carries the heel gripping device.

The heel gripping device comprises the lower plate 35 and the upper plate 36 which plates are disposed in substantially the same vertical plane and have the adjacent edge portions 37 thereof curved and adapted to fit inthe crease between the heel seat and the heel or the shoe 38. The lower plate 35 is stationary, it being secured to the bar 34 bythe screws 39 in this instance, and the up per plate 36 is secured by the screws 39 to the angular arm 40 which latter has thereon the pivot 41which bears in the upper part of the rearward and upward extension 42 on the bar 34. The forward part of the edge portion 37 on one or both of the plates 35 and 36 is formed with teeth 43 adapted to hold and prevent forward movement of theshoe when the heel is moved against a cutter. The plate 36 may be provided on theside thereof with the auxiliary plate 44 which is securedto the plate 36 by the screws 39 and is provided with the teeth 45 which are adapted to engage the heel of the shoe 38 and prevent movement of the heel when it 'is moved against the cutter. The portion of the auxiliary plate 44 with the teeth 45 thereon is offset or spaced from the plate 36 so that the operator has an unobstructed view when lacing the plate 36 in the crease of the shoe 38. The teeth 45 terminate short of the edge of the edge portion 37 so as not to prevent the edge portion 37 from extend ing into the crease of the shoe 38. The plate handle may be connected.

may also havel on theside thereof an auX iliary plate 14: which is secured by the screws 39 and is similar to the auxiliary plate 11% already described. A: washer 45" 15 disposed at one side of the extension 42,011 the pivot 41, and a spacing washer 46' is disposed on saidpivot between the extension 42 and the arm 40.

The arm L0 is connected'to the part 32pby; the spring 46, and said arm 40 has at its lower end a curved lateral extension- 4r7 in:

contact with the curved upper end 48: of? the angular: lever 49 which latter is ;pivotally mounted on the sleeve-13.: An operating. to the angular lever 4L9, or. afoot lever 51 mounted on.the pivot 52 onthe frame 10.:may be pivotally' connectedto the rod 53 which'latteris pro, vided with the knucklejoints 54: and: 55; AJ- spring56 is suitably connected" between the frame 10 and the lever spring 5.7 which is stronger 56is suitably connected between the frame 10 and the abutment 58,- which latter is mounted on the pivot 52 and bears against the underside of the; lever 51. A; shoulder 59cm the abutment 58 normally contacts with the stop 60 onzthe frame lO-to 'limit; the upward movement of the abutment 58.

The cuttery 61 preferably consists Of! a bandsaw which passes around the pulleys 62 and 63. which are mountedon the shafts 64b and- 65v which latter are journaledl in suitable bearings 66 and.67i on the-frame 10.- A suitable device indicated at68 is mounted on; the frame 10 to guide a and placement of the bandsaw61-.. As shown, the

shaft 65 may-be driven by theelectric motor;-

69Iwhich has on its shaft 70fithe spur pinion 71 in;mesh withtthe spur wheel'72on1 the shaft 65. The bar: 34 whichmarries the-shoe gripping device; can be locked? in: adjusted the part 32 by turning the 1 winged set-screw '73 which ismounted: onthe part 32- andadapted to frictionallyengage the lug 74 which is provided on the position on underside of the bar 34- and mounted on the pivot A winged set screw 7 5 on the arm- 30 canbe turnedto engage the part 32. and

loelcthe-latter in adjusted position; in-v the-1 socket 31;

From the foregomgthe construction, man ner of use, and: advantages of the mventiomwill be apparent to those skilledvinthe art. ltiwill be seen that when theheel ofithe-shoe.

38 isaplaced in position on the;stationany plate 35, the handle 23 may be operated, to

move'the sleeve 13 transversely on=the-shaft;

12 fr and in consequence move the heel 1 transversely to the cutter 61- according to. the. amount that is to becut: oifi of the heel. If. it is desired; to make an angularv eutlongie. tudinally of: the heelthe setscrew 75 is loosened and then the part! 32 is turned: to turnzthe. heel according; to theaangleirequired 51', and another. than thespring prevent dis- I whereupon the part 32 is locked in adjusted position by tightening the set-screw 75.

it is desired to make an angular out transversely-of the heel; the set-screw 73 is loosenedand then] the bar 34: is turned on the 70 pivot 33' to tilt the heel transversely to the cutter 61, so that the latter will out the heel to have'either side of the heel thicker'than thelotherzside-n By pulling up on the handle 50 or by pressing down on the lever 51 the 75 angular lever d9iandethe -angular arm 40" meV moved. to cause the plates .35 :1 and 36 to gripthe shoe 38-ianditoihave the auxiliary platesaiiand 4L4! engagethe heel of the shoe, whereuponi further. pressure on the lever 51. results in. moving the heel; in} a; curved path so .thatthe heeliscutzby'the cutter 61.

The construction which has: been. particularly illustrated and. described: .admits of: changes, and; modifications-whenefore the 5 a right is reserved to all: suchchanges andmodifications as donot depart from: the spirit and scope of the invention which is defined inthe appendedi elaims- 1.
